2.3 Ports
This topic describes the features, numbering rules, names, types, and quantity of the CX320
ports.
The CX320 provides ports for users to operate and configure. The ports are used to send and
receive data.
The CX320 Ethernet ports are numbered in the Slot number/Subcard number/Port number
format.
l Slot number indicates the slot number of the current switch module. The value ranges
from 1 to 4, mapping to slot numbers 1E, 2X, 3X, and 4E.
l Subcard number indicates the number of a subcard with ports. The value ranges from 1
to 22. For details, see Table 2-2, Table 2-3, and Table 2-4.
l Port number indicates the serial number of the port on the subcard. For details, see Table
2-2, Table 2-3, and Table 2-4.
For example, if the CX320 is in slot 2X, the first optical Ethernet port on the upper right of
the panel is numbered 40GE 2/20/2, as shown in Figure 2-9.
